About TheXero

I’m a penetration tester, exploit developer, and wireless security specialist with over a decade of hands-on research. I’ve spent years digging into the guts of protocols, binaries, and wireless stacks — and this site is where I document that work.

What I Do

Penetration Testing — From web applications and infrastructure to wireless networks and physical security assessments. I work with organisations to find weaknesses before the wrong people do.

Exploit Development — I write about buffer overflows, SEH exploits, egghunters, shellcoding, and bypass techniques. The exploit development series on this site takes you from a crash to a working shell, step by step.

Wireless Security Research — Wi-Fi is broken in interesting ways. I research 802.11 attack techniques including rogue access points, PMKID harvesting, EAP downgrade attacks, and the abuse of open network encryption. My WiFi Attacks Specialist training course teaches these techniques in depth.

Security Advisories — I practice responsible disclosure and have reported vulnerabilities to vendors across software and hardware. Published CVEs are listed in the Advisories section.

Why This Site Exists

Security research shouldn’t live in paywalled PDFs or forgotten slide decks. This site exists to make quality technical content freely available — the kind of detail that actually helps you understand what’s happening at the packet, register, and byte level.

No filler. No AI-generated fluff. Just the real work.
